Abstract (en)

A display apparatus includes: a display panel configured to display an image based on input image data; a gate driver configured to output a gate signal to the display panel; a data driver configured to output a data voltage to the display panel; and a driving controller configured to control an operation of the gate driver and an operation of the data driver, to determine a driving mode of the display apparatus to one of a normal driving mode and a low frequency driving mode based on the input image data, and to determine a driving frequency of the display panel based on the input image data, wherein the driving controller is configured to determine the driving frequency of the display panel using a flicker value varied according to a grayscale value of the input image data and a luminance setting value.
